Have you ever noticed what happens to an idea once you express it?Just talking about it or writing it down causes you to make it clear in your own mind.How can you use this to increase your brain power?Start writing.

    By putting thoughts into words,you are telling yourself the logic behind what you think,feel,or only partly understand.Often,explaining a thought is the process of understanding.In other words,you increase your brain power by exercising your “explain power”.

    Another benefit of writing is that it helps you remember.Many,if not most,highly productive people are always taking notes.You can try keeping it all in your head,but if you keep a journal of your ideas,the next time you're working on a big project,you'll probably have more success.

    Want to understand a topic?Write a book about it.That's an extreme example,but if you are learning something new,write a letter to a friend about it,and you will understand it better.Want to invent something?Write an explanation of the problem—why you want to solve it,and why it is worth solving,and you're halfway there.

    Writers don't always write because they clearly understand something beforehand.Often,they write about something because they want to understand it.You can do the same.Writing will help bring you to an understanding. Give it a try.

     “Sugar, alcohol and tobacco,” economist Adam Smith once wrote, “are commodities which are nowhere necessaries of life, which have become objects of almost universal consumption, and which are, therefore, extremely popular subjects of taxation.”

    Two and a half centuries on, most countries impose (征税) sort of tax on alcohol and tobacco. With obesity levels putting increasing pressure on public health systems, governments around the world have begun to toy with the idea of taxing sugar as well.

    Whether such taxes work is a matter of debate. A preliminary review of Mexico's taxation found a fall in purchases of taxed drinks as well as a rise in sales of untaxed and healthier drinks. By contrast, a Danish tax on foods high in fats was abandoned a year after its introduction, during claims that consumers were avoiding it by crossing the border to Germany to satisfy their desire for cheaper, fattier foods.

    The food industry has, in general, been firmly opposed to such direct government action. Nonetheless, the renewed focus on waistlines means that industry groups are under pressure to demonstrate their products are healthy as well as tasty.

    Over the past three decades, the industry has made some efforts to improve the quality of its offerings. For example, some drink manufactures have cut the amount of sugar in their beverages (饮料).

    Many of the reductions over the past 30 years have been achieved either by reducing the amount of sugar, salt or fat in a product, or by finding an alternative ingredient. More recently, however, some companies have been investing money in a more ambitious undertaking: learning how to adjust the fundamental make-up of the food they sell. For example, having salt on the outside, but none on the inside, reduces the salt content without changing the taste.

    While reformulating (再制定) recipes is one way to improve public health, it should be part of a multisided (多边的) approach. The key is to remember that there is not just one solution. To deal with obesity, a mixture of approaches, which include reformulation, taxation and adjusting portion sizes, will be needed. There is no silver bullet.

    Back to its origin

    The University of Sheffield is a research university in the city of Sheffield in South Yorkshire, England. It is one of the original “red brick” universities, which are a group of top and famous old universities. The University of Sheffield was originally formed by the combination of three colleges. The Sheffield School of Medicine was founded in 1828, followed in 1879 by the opening of Firth College by Mark Firth, a steel manufacturer (制造商), to teach arts and science subjects. Firth College then helped to provide money for the opening of the Sheffield Technical School in 1884 to teach applied science. In 1897 the three institutions were joined together to form the University College of Sheffield, which in turn became the University of Sheffield by Royal Charter (特许) in 1905. This university is famous for its good education and boasts a number of Nobel Prize winners among its former students.

    More information

    System: The University has five departments: Arts and Humanities; Engineering; Pure Science; Social Sciences; Medicine, Dentistry and Health. Sheffield also has many research programs in fields including aerospace, environmental science, psychology, and biology.

    City show: Sheffield is a lively city in the north of England. Sheffield is known as the greenest city in Europe because of its 2 million trees. As a result, there are many parks and woods throughout the city and beyond. Sheffield is the greenest city in England with 150 woodlands and 50 public parks within the city. Once, in Sheffield, the folk hero—Robin Hood lived in Sherwood Forest with 150 of his loyal friends. And Charlotte Bronte, the English writer noted for her novel Jane Eyre was born in Sheffield.

Why do we talk the way we do? It might date back to when our ancestors left the jungle for the open plain. Between 5. 3 million and 16 million years ago, Africa's landscapes changed from thick, leafy forests to wide-open grasslands. This environmental change pushed our ancestors out of the trees and onto the ground. Along with all of the physical and behavioral changes this may have caused, researchers also believe it may have changed the way we speak. 

"Open landscapes provide us with fewer objects to affect signal communication, meaning our voices can travel further compared with that in thick forests, " Charlotte Gannon, a researcher who studies language development, told Newsweek. "The move to these open spaces may have increased the effectiveness of our communication. "

By comparing the vocal calls of the orangutan (大猩猩) , Gannon and her team were able to establish how different calls could travel across different landscapes. In their study, the team played 487 calls from orangutans and measured their audibility (可听度) at set length over an overall distance of over 1, 300 feet in the South African plain. 

"Our results were surprising, " Gannon said, "The rule of sound spread suggests that lower-frequency ( 低频率) sounds (the grumphs) would have traveled further than higher-frequency sounds (the kiss squeaks). Our results actually found the opposite to this. " In these environmental settings, consonant (辅音)-like calls traveled a lot further than vowel ( 元 音 ) -like calls. Actually, around 80 percent of consonant-based calls were audible at 1, 300 feet, compared to only 20 percent of vowel-based calls. 

Gannon said these results highlight the importance of studying living orangutan to learn about our species' history. "We can view them as time machines that allow us to recreate key moments of our history so we can learn more about the development of our language, " Gannon said. "Despite their popularity in modern languages, consonants have often been forgotten when discussing speech development. Our research highlights not only their presence in ancient times but their importance to the development of language. "

"I'm going to fail!" My best friend cried. She and I had this conversation almost every day while we were in high school.
    The truth was that my friend never failed in any subjects. I just think that she can't accept failures because she lives her life as a perfectionist. What she fails to understand is that a lot of good can come from failures.
    For example, failure can help build relationships. Once I was cooking dinner for a friend, I was tired, and several dishes I tried to make turned out bad. I grew more and more upset until my friend told me that I shouldn't worry. She cared more about our friendship than the dishes. That day, I learned that failure doesn't always make people dislike you. In fact, after she said those words to me, I grew closer to her.
    Failure can make success evermore exciting. Every few years, there would be an important test in the PE class at our school. Students had to run a mile within eight minutes. I was never good at running, so I failed every time until the third year at school. Then I began working out regularly, and yet still failed that year. A few days later, however, the teacher gave me and some other students another chance to run and I got a pass finally! You can't imagine how excitedly I was after that. I felt the memory of the success was as sweet as honey, because I had to overcome failure to reach it.
    Now it's clear to see that failure can teach us good lessons. It's not an end, but it can be a beginning
